Use this calculator to determine the work done in kilocalorie, joule, kilojoule, kilowatt-hour, electronvolt, british thermal unit, foot-pound or newton-metre units, from the power output and the time taken.
The formula used by this calculator to determine the work done from the power output and elapsed time is:
W = P · t
- W = Work done or energy transferred
- P = Power output
- t = Time duration
This is the rate at which energy is transferred.
This is the total elapsed time.
This is the total energy transferred or work done.
